The suggestion by Drs. Alves-Rodrigues and Thomas that the cardioprotective effect of green leafy vegetables may be related to high lutein levels is based on an animal study of lutein and arteriosclerosis (1) and a study among humans examining the relation between lutein and other antioxidants and coronary disease (2). In our study, we mentioned that antioxidant vitamins, folate, fiber, and such minerals as potassium may contribute to the apparent beneficial effects of fruits and vegetables, and we agree that lutein may also partly explain this benefit.
